Description
Technical Field
The present invention relates to a vibration isolation device and a shock absorber for supporting vibration isolation of a vibrating member such as an engine to a non-vibrating member such as a vehicle body.
Background
A shock absorber used in a vehicle such as an automobile includes: a vibration side bracket (blacket) mounted to the engine; a non-vibration side bracket mounted to the vehicle body; and a vibration-proof device (engine mount) provided between the vibration-side bracket and the non-vibration-side bracket.
The vibration isolation device is provided with: a first mounting member mounted to the vibration side bracket; a second mounting member mounted to the non-vibrating side bracket; and an isolator (insulator) disposed between the first mounting member and the second mounting member.
As the above-described damper device, there is a damper device in which a locking portion is formed in a non-vibration-side bracket and a stopper portion (rebound stopper) opposed to the locking portion is formed in a first mounting member (for example, see patent document 1). In this configuration, the stopper portion abuts against the locking portion, thereby limiting the extension amount of the vibration damping device (the movement amount of the first mounting member).
Further, there is also a structure in which a stopper portion is extended from the vibration-side bracket so as to face the engagement portion of the non-vibration-side bracket.

Problems to be solved by the invention
As described above, in the structure in which the stopper portion of the vibration isolator or the vibration-side bracket abuts against the locking portion of the non-vibration-side bracket, it is preferable that the locking portion is covered with the rubber member to prevent a hitting sound when the stopper portion and the locking portion come into contact with each other. However, since a metal mold for covering the engaging portion with the rubber member is required, there is a problem that the manufacturing cost of the non-vibration side bracket increases.
Further, when the stopper portion is formed on the vibration-side bracket, the vibration-side bracket is enlarged, which causes a problem that the weight of the vibration-side bracket is increased.
An object of the present invention is to solve the above-described problems and to provide a vibration isolator and a damper that can reduce the manufacturing cost of a bracket attached to a vibrating member and a non-vibrating member and can reduce the size and weight of the bracket.
Means for solving the problems
In order to solve the above problem, the vibration isolator of the present invention is provided between a vibration-side bracket attached to a vibration member and a non-vibration-side bracket attached to a non-vibration member. The vibration isolation device is provided with: a first mounting member mounted to the vibration side bracket; a second mounting member mounted to the non-vibrating side bracket; and a spacer disposed between the first mounting member and the second mounting member. The first mounting member is provided with a stopper portion facing the engaging portion formed on the non-vibration-side holder. The spacer is provided with a covering portion for covering at least a surface of the stopper portion facing the engaging portion.
In the vibration damping device according to the present invention, the stopper of the first mounting member abuts against the locking portion of the non-vibration bracket, whereby the extension amount of the vibration damping device can be limited. Further, since the stopper is covered with the covering portion of the isolator, it is possible to prevent hitting noise when the stopper comes into contact with the locking portion.
In the vibration damping device according to the present invention, the stopper portion is covered with the covering portion of the isolator, so that it is not necessary to cover the locking portion of the non-vibration side bracket with a rubber member. Accordingly, the number of metal molds used for manufacturing the non-vibration bracket can be reduced, and thus the manufacturing cost of the non-vibration bracket can be reduced.
In addition, in the vibration damping device according to the present invention, since it is not necessary to form the stopper portion on the vibration-side bracket, the vibration-side bracket can be made smaller and lighter, and the manufacturing cost of the vibration-side bracket can be reduced.
In the vibration damping device, when a region of the first mounting member facing the end surface of the locking portion is covered with the covering portion, hitting noise can be prevented when the first mounting member and the locking portion come into contact with each other.
The buffer device of the invention comprises: a vibration side bracket mounted to the vibration member; a non-vibration side bracket mounted to the non-vibration member; and the vibration isolator is arranged between the vibration side bracket and the non-vibration side bracket. The non-vibration side bracket includes a first bracket to which the vibration isolator is attached, and a second bracket attached to the first bracket, and the engaging portion is formed on the second bracket.
In the shock absorber according to the present invention, by using the vibration isolator, the bracket can be made smaller and lighter while preventing rattling noise when the stopper portion comes into contact with the engagement portion, and the manufacturing cost of the bracket can be reduced.
In the shock absorber according to the present invention, the second bracket may be attached to the first bracket after the vibration isolator is attached to the first bracket. That is, in the present invention, the vibration damping device having the stopper portion can be easily assembled to the non-vibration side bracket.
Effects of the invention
In the vibration isolator and the damper according to the present invention, the manufacturing cost of the bracket can be reduced, and the bracket can be made smaller and lighter. Further, in the shock absorber of the present invention, the vibration isolator can be easily attached to the bracket.

Detailed Description
Embodiments of the present invention will be described in detail with reference to the accompanying drawings as appropriate.
As shown in fig. 2, a shock absorber 1 of the present embodiment is a device provided between an engine 2 (a "vibrating member" in the claims) and a vehicle body 3 (a "non-vibrating member" in the claims) of a vehicle such as an automobile.
Further, the vibration member refers to a generation source of vibration (for example, an engine, a motor, and the like). The non-vibration member is a member (for example, a vehicle body or the like) to which vibration of the vibration member is not intended to be transmitted.
The shock absorber 1 includes: a vibration side bracket 50 attached to the engine 2; a non-vibration side bracket 60 attached to the vehicle body 3; and a vibration isolator 10 (see fig. 1) provided between the vibration-side bracket 50 and the non-vibration-side bracket 60.
The vibration side bracket 50 is a metal member. The vibration-side bracket 50 is formed with an engine mounting portion 51 to be mounted on the engine 2 and a vibration isolator mounting portion 52 to be mounted on the vibration isolator 10 (see fig. 1).
The engine mounting portion 51 is formed with a plurality of through holes 51 a. The engine mounting portion 51 is fixed to the engine 2 by a bolt (bolt) (not shown) inserted through the through hole 51 a.
The vibration isolator mounting portion 52 extends laterally from the engine mounting portion 51. A through hole 52a is vertically inserted through the distal end of the vibration isolator mounting portion 52.
The non-vibrating side bracket 60 is a metal member. The non-vibrating side bracket 60 has a first bracket 60a and a second bracket 60b mounted to an upper portion of the first bracket 60a. Thus, the non-vibrating bracket 60 is divided into two upper and lower members.
The first bracket 60a is formed with a vehicle body attachment portion 61 to be attached to the vehicle body 3, a vibration isolator attachment portion 62 to be attached to the vibration isolator 10, and a connecting portion 63 (see fig. 1) to which the second bracket 60b is attached.
The opening 62a of the vibration isolator mounting portion 62 is a portion for press-fitting the second mounting member 30 of the vibration isolator 10 described below.
The vehicle body mounting portion 61 of the first bracket 60a protrudes downward from the vibration isolator mounting portion 62. A plurality of through holes 61a (see fig. 1) are formed in the lower end portion of the vehicle body attachment portion 61. The vehicle body attachment portion 61 is fixed to the vehicle body 3 by a bolt (not shown) inserted through the through hole 61 a.
The connecting portion 63 of the first bracket 60a protrudes upward from an upper end portion (upper end portion on the left side in fig. 2) of the vibration isolator mounting portion 62. A screw hole (not shown) is formed in the upper surface of the connecting portion 63.
The second bracket 60b is formed with a connecting portion 64 to be attached to the first bracket 60a, a vehicle body attachment portion 65 to be attached to the vehicle body 3, and a locking portion 66 (see fig. 1) that restricts the upward extension of the vibration damping device 10.
The connecting portion 64 of the second bracket 60b is a portion attached to the upper surface of the connecting portion 63 of the first bracket 60a. A plurality of through holes 64a (see fig. 1) are formed through the connection portion 64 of the second bracket 60b. The both connection portions 63 and 64 are connected by screwing a bolt (not shown) inserted into the through hole 64a into a screw hole (not shown) of the connection portion 63 of the first bracket 60a.
The vehicle body mounting portion 65 of the second bracket 60b protrudes outward (left side in fig. 2) from the connecting portion 64. A through hole 65a (see fig. 1) is formed in a distal end portion of the vehicle body mounting portion 65. The vehicle body mounting portion 65 is fixed to the vehicle body 3 by a bolt (not shown) inserted through the through hole 65 a.
The locking portion 66 protrudes inward (rightward in fig. 2) from an upper portion of the connecting portion 64. The distal end of the locking portion 66 is disposed directly above the opening 62a of the first bracket 60a.
The vibration isolator 10 is a liquid-filled engine mount provided between the vibration-side mount 50 and the non-vibration-side mount 60.
The vibration isolation device 10 includes: a first mounting member 20 mounted to the vibration-side bracket 50; a second mounting member 30 mounted to the non-vibrating side bracket 60; and a spacer 40 disposed between the first mounting member 20 and the second mounting member 30.
The first mounting member 20 is a metal member that is insert-molded (insert) into the upper end of the separator 40.
The first mounting member 20 is formed with a mounting portion 21 for mounting the vibration-side bracket 50. A screw hole 21b is formed in the center of the upper end surface of the mounting portion 21.
The first mounting member 20 is provided with a flat plate-like stopper portion 22 extending from the mounting portion 21 toward the second bracket 60b (left side in fig. 2).
As described below, the stopper 22 is a rebound stopper that limits the upward extension amount (upward movement amount of the first mounting member 20) of the vibration damping device 10 by abutting against the lower surface 66a of the locking portion 66.
The second mounting member 30 is a cylindrical metal member into which the lower end portion of the isolator 40 is fitted.
A flange portion 31 protruding outward is formed at an upper opening edge portion of the second mounting member 30.
The isolator 40 is a rubber elastic member formed in a substantially truncated cone shape. An inner space opened downward is formed at a lower portion of the separator 40.
The first mounting member 20 is insert-molded at an upper end portion of the spacer 40.
Further, the spacer 40 is formed with a covering portion 45 that covers the outer peripheral surface 21a of the mounting portion 21 of the first mounting member 20 and the stopper portion 22.
In the present embodiment, the first mounting member 20 is covered with a rubber member substantially entirely, and only the upper end surface of the mounting portion 21 is exposed to the outside.
The lower end of the spacer 40 is formed in a cylindrical shape along the inner peripheral surface of the second mounting member 30, and is vulcanization bonded to the inner peripheral surface of the second mounting member 30.
A partition member 41 made of resin is mounted inside the separator 40. The internal space of the separator 40 is partitioned vertically by the partition member 41.
A main liquid chamber 11 is formed above the partition member 41. The main liquid chamber 11 is a space surrounded by the inner surface of the spacer 40 and the upper surface of the partition member 41, and is filled with a non-compressible working liquid.
A diaphragm (diaphragm)42 made of rubber is attached to the inside of the separator 40 below the partition member 41. The diaphragm 42 closes the opening on the lower side of the separator 40.
An auxiliary liquid chamber 12 is formed between the partition member 41 and the diaphragm 42. The auxiliary liquid chamber 12 is a space surrounded by the lower surface of the partition member 41 and the upper surface of the diaphragm 42, and is filled with a non-compressible working liquid.
An orifice (orifice) passage 41a for communicating the primary liquid chamber 11 and the secondary liquid chamber 12 is formed in the partition member 41.
As shown in fig. 3, a mounting structure of the vibration isolator 10 to the vibration-side bracket 50 and the non-vibration-side bracket 60 will be described.
In a state where the second bracket 60b is detached from the first bracket 60a of the non-vibration bracket 60, the second mounting member 30 is press-fitted into the opening 62a of the vibration isolator mounting portion 62 from above.
Further, since the flange portion 31 of the second mounting member 30 is in contact with the opening edge portion of the opening 62a from above, the second mounting member 30 is configured not to be detached downward from the opening 62a.
After the second mounting member 30 is assembled to the first bracket 60a, the connection portion 64 of the second bracket 60b is connected to the connection portion 63 of the first bracket 60a.
Accordingly, the stopper 22 of the first mounting member 20 is disposed directly below the locking portion 66 of the second bracket 60b.
The stopper 22 and the locking portion 66 are arranged at a vertical interval, and the upper surface 22a of the stopper 22 faces the lower surface 66a of the locking portion 66.
In the present embodiment, the covering portion 45 covering the upper surface 22a of the stopper portion 22 contacts the lower surface 66a of the locking portion 66.
The stopper 22 of the first mounting member 20 is disposed on the side of the connecting portion 64 of the second bracket 60b. The stopper portion 22 and the connecting portion 64 are arranged at a spacing in the lateral direction.
The outer peripheral surface 21a of the mounting portion 21 and the locking portion 66 of the second bracket 60b are arranged with a space in the lateral direction.
The vibration isolator mounting portion 52 of the vibration side bracket 50 is placed on the upper end surface of the mounting portion 21 of the first mounting member 20. Then, the first mounting member 20 is mounted to the bracket 50 on the vibration side by screwing the bolt B inserted through the insertion hole 52a of the vibration isolator mounting portion 52 into the screw hole 21B of the mounting portion 21.
In this way, the vibration isolator 10 mounted on the brackets 50 and 60 has the following structure: the vibration input from the engine 2 via the vibration side bracket 50 is absorbed by the elastic deformation of the isolator 40.
The vibration isolation device 10 is configured to have the following structure: when the isolator 40 is elastically deformed by vibration, the working fluid flows through the orifice passage 41a, and liquid column resonance occurs in the orifice passage 41a, thereby damping the vibration.
Further, when the spacer 40 is extended upward and the first mounting member 20 is moved upward, the stopper 22 abuts against the lower surface 66a of the locking portion 66, thereby restricting the amount of upward movement of the first mounting member 20.
In this way, the stopper 22 and the locking portion 66 set the amount of upward expansion of the vibration isolator 10, i.e., the maximum amplitude of the vibration isolator 10.
In the shock absorber 1 as described above, the stopper portion 22 of the vibration damping device 10 is covered by the covering portion 45 of the spacer 40. Therefore, the hitting noise can be prevented when the stopper portion 22 comes into contact with the locking portion 66 of the non-vibration bracket 60.
In the vibration damping device 10, the stopper 22 is covered by the covering portion 45 formed integrally with the spacer 40. Therefore, it is not necessary to cover the engaging portion 66 of the non-vibration side bracket 60 with a rubber member as in the conventional art. Accordingly, the number of molds used to manufacture the non-vibration bracket 60 can be reduced, and therefore, the manufacturing cost of the non-vibration bracket 60 can be reduced.
In addition, in the shock absorber 1, since it is no longer necessary to form the stopper portion on the bracket 50 on the vibration side, the bracket 50 on the vibration side can be made smaller and lighter, and the manufacturing cost of the bracket 50 on the vibration side can be reduced.
In the vibration damping device 10, the outer peripheral surface 21a of the mounting portion 21 of the first mounting member 20 is covered with the covering portion 45 of the spacer 40. Therefore, it is possible to prevent rattling noise when the attachment portion 21 comes into contact with the locking portion 66 of the non-vibration side bracket 60 due to the lateral movement of the first attachment member 20.
In the shock absorber 1, the non-vibration side bracket 60 is divided into the first bracket 60a and the second bracket 60b.
In this structure, as shown in fig. 3, the second bracket 60b is detached from the first bracket 60a in advance before the vibration isolator 10 is assembled to the non-vibration side bracket 60. Then, after the vibration isolator 10 is attached to the first bracket 60a, the second bracket 60b is attached to the first bracket 60a. Accordingly, as shown in fig. 2, the locking portion 66 of the second bracket 60b can be opposed to the stopper portion 22 of the first mounting member 20 above the stopper portion 22 of the first mounting member 20. In this way, the vibration isolator 10 having the stopper 22 can be easily assembled to the non-vibration side bracket 60.
The embodiments of the present invention have been described above, but the present invention is not limited to the embodiments, and can be modified as appropriate within a range not departing from the gist thereof.
For example, in the present embodiment, as shown in fig. 2, the upper surface 20a of the first mounting member 20, the outer peripheral surface 21a of the mounting portion 21, and the stopper 22 are entirely covered with the cover 45, but at least the upper surface 22a of the stopper 22 may be covered with the cover 45.
In the present embodiment, the entire outer peripheral surface 21a of the mounting portion 21 of the first mounting member 20 is covered with the cover portion 45, but it may be: at least the region of the outer peripheral surface 21a of the mounting portion 21 that faces the locking portion 66 of the non-vibration bracket 60 is covered with the cover portion 45.
The shock absorbing device 1 of the present embodiment is provided between the engine 2, which is a vibrating member, and the vehicle body 3, which is a non-vibrating member, but the vibrating member and the non-vibrating member to which the shock absorbing device and the anti-vibration device of the present invention can be applied should not be limited thereto.
